You can find the li= st of these tests at the end of this mail. Trying to downgrade to the lates= t commit of the current release branch of gcc 12 (so gcc 12.2.1) make all m= y glibc test failure disappear. Checking randomly couple of the .out files = of the failing tests, it seems these test don=E2=80=99t work at all with gc= c 13, there are many errors, and it doesn=E2=80=99t seem it=E2=80=99s due t= o a small change of precision. Am I the only one to experiences these test = failure ? In case you don=E2=80=99t have such errors in the same conditions= , how shall I report these errors for investigation ? Just the .out file wo= uld be enough ? I don=E2=80=99t know anything about these math/ tests, it= =E2=80=99s the first time I see them failing like this. This might be GCC bug 107879 (https://gcc.gnu.org/PR107879 ) or GCC bug 107608 (https://gcc.gnu.org/PR107608 ) . I am suspecting the first one. Jakub has a fix which he is I suspect will be submitting tomorrow too.
